citizen of the United sas City7 in the county States, residing at KanofVyandotte, State of Kansas, have invented a certain new and usefulImprovement in Apparatus for IIeat scription, reference Io panyingdrawings, forming specification, wherein` Figure lis a verticalsectional view through my improved apparatus. sectional view on line 22, Fig. l.

The essential features of this present invention reside in the peculiarvconstruction and arrangement of the heater, whereby the radiated heatis equalized and evenly distributed throughout the barrel or Cask; inthe 3o provision of a plate or lid slidiri'gly supported on the heater,which is adapted, when the el, to accommoas a cover to heater is loweredinto the bari' date itself to the top of the barrel and serve tainedheat, vice on the prevent the escape of the conand in arranging acenterin g deupper portion of the heater, said centering device beingadapted to project down through the suspended lid after said lid restsupon a barrel to center the heater 4o relative to the barrel; and,further, the invention consists in ment, and combin all as will hereinafand afterward In the drawing which is slightly the construction,arrangeation of the several parts, ter be more fully described,

through which the waste products of combustion are carried o.

This smoke-pipe consists of a stationary section D,passing through theceiling, or to asuitable section D, sleeved on said and secured at itsportion of the heate The upper end of D is formed with flange CZ',through t pass guide-rods E, depending from the ceiling and connected attheir lower ends to a ring c, which ring e serves to hold the lower endssliding pipe-section F and F Iof therods in position and also to guidethe indicate guide-arms the inner ends of which are fastened, preferablyintegral, to rings which are secured to the or dome-section o whiletheir outer ends or posts G.

The more intense tion of the heater,

the heater and a centering device arranged on the upper part oftheheater which projects through the lid when the heater is lowered andcenters the heater relative to barrels of different sizes, the lidaccommodating itself to barrels of different heights to retain the heatin the barrel being heated, substantially as described.

2. In an apparatus for heating and drying barrels, the combination witha heater which is adapted to be moved into, or out of, the barrel to beheated, and a plate or lid, suspended from said heater by flexible cordsor chains,which plate or lid is adapted to accommodate itself to barrelsof varying heights; substantially as described.

3. In an apparatus for heating and drying barrels, the combination witha counterbalanced heater, adapted to be lowered into the barrel to beheated or dried, means on the heater for centering the heater relativeto the barrel, and a plate or lid carried by the heater and adapted toseal the barrel when the heater is lowered t-hereinto; substantially asdescribed.

4. In a barrel-heater, the combination with the fire-pot, of abaffle-cylinder surrounding the lower portion of said fire-pot, andspaced therefrom, whereby, the radiation of heat is equalized throughoutthe exterior of the heater; substantially as described.

5. In a barrel-heater, the combination with a cylindrical .fire-pot, ofan open-ended perforated cylinder surrminding the lower portion of saidfire-pot, for promoting a circula tion of the heated air; substantiallyas described.

G. In a l awel-heater, the combination with a cylindrical lire-pot, of aperforated cylinder, of larger diameter than the fire-pot, arrangedaround the lower portion of the firepot, and rods secured to a i langeon the upper portion of the lire-pot, for suspending said perforatedcylinder, whereby, a space is left between the perforated cylinder audfire-pot, and at the ends of the perforated cylinder; substantially asdescribed.

7. In an apparatus for heating and drying barrels, the combination witha heater which is adapted to be moved into, or out of, the barrel to beheated, aplate or lid, suspended from said heater by flexible cords orchains, which plate or lid is adapted to accommodate itself 'to barrelsof varying heights, and one or more peep-holes in said plate or lid;substantially as described.

In testimony whereof I hereunto affix my signature, in presence of twowitnesses, this 23d day of October, 1896.

and, owing to the air-space and an updraft, part of said heat is drivenupward and commingled with the heat radiating from the upper portion ofthe heater. Thus it will be seen'that the heat is practicallydistributed evenly throughout the interior of the barrel.

II indicates an annular plate which is supported from the upper portionof the heater by flexible cords or chains h. This plate I-I is adaptedto rest upon the top of the barrel when the heater is lowered thereintoand close the opening to confine the heat within the barrel.

h' indicates peep-holes covered with mica, through which the operatormay see the condition of the barrel during the heating and dryingperiod.

The operation of my invention is as follows: The barrel is formed over asuitable form, the slaves having been steamed, as is usual, tofacilitate their being bent to proper shape. The form is then removedand the barrel placed upon the platform A over the opening a, it beingof course understood that the barrel is not headed at either end. Theheater is now lowered 'into the barrel, the plate II covering the barrelto retain the heat within, so that full benefit may be derived from theradiated heat. After the barrel has become sufficiently dry and thestaves set the heater is raised from the barrel, the barrel removed, andanother placed in position and the operation repeated.

By my improved construction a simple, compact, and efficient apparatusis produced and one which is convenient and easy to manipulate. Itsadvantages over the style of apparatus wherein the barrel has to beelevated up to the heater are obvious.

My special construction of heater is far superior to those heretoforeemployed, as practical usage has demonstrated that a barrel may bethoroughly dried without scorching or charring the wood, which was notthe case heretofore, because the more intense heat from the lowerportion of the heater would invariably scorch the wood at the lower partof the barrel before the upper part had been properly dried.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my apparatus can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

l. In an apparatus for heating and drying barrels, the combination witha counterbalanced heater, adapted to be moved into, or out of, thebarrel to be heated, of a plate or lid iiexibly suspended from the upperpart of Witnesses:
